Abstract
The capacity of W-CDMA systems in which base stations are equipped with adaptive antennas (AA) is investigated in mixed service scenarios. The simulations show that generally, a threefold downlink (DL) capacity increase can be gained by employing a fixed or steered beam antenna system. For some scenarios, DL capacity gains of 4 to 6 times can be achieved. Further, a DL capacity comparison between the steered beam concept and the fixed (multi) beam AA concept is presented
